Light into Polymers Makes Money Spectroscopy for In-Situ Analysis of Molecular Weight, Melt Index, Degradation and Polymerisation

摘要

Simple and cheap spectroscopic measurements, in the laboratory, near-line and online, are being increasingly used to characterise polymers, monitor the production process and follow degradation mechanisms. The application of these techniques to production permits the real-time measurement of those quality variables that form the polymer manufacturing specification, such as molecular weight, density, and melt index. We will illustrate developments using examples in siloxane, cellulose and polyolefin manufacture.
